Functions to read and write semidefinite program data and solutions in SDPA format.

1 2 3 4 |

`file` |
The name of the file to read from or write to. |

`C` |
Block structured cost matrix |

`A` |
List of block structured constraint matrices |

`b` |
RHS vector |

`K` |
Cone specification, as used in |

`X` |
Block structured primal optimal solution matrix |

`Z` |
Block structured dual optimal solution matrix |

`y` |
Dual optimal solution vector |

`verbose` |
Printout information as problem is read. Passed to CSDP's readsdpa function. Default |

`m` |
Number of constraints in problem. |

Block structured matrices must be specified as described in
`csdp`

.
Files read must be in SDPA format (see
http://euler.nmt.edu/~brian/sdplib/FORMAT).
However, these functions don't support comments or grouping characters
(e.g. braces, parentheses) in the block sizes specification.

Function `readsdpa`

returns a list with elements `C,A,b,K`

.
Function `readsdpa.sol`

returns a list with elements
`X,Z,y`

.
All returned matrices are lists of objects of class `simple_triplet_sym_matrix`

.
